Danny Green missed a layup with 0.9 seconds left in regulation that could have won the game for the Spurs. Scola drove around Duncan for a layup with 5.8 seconds left on the previous possession to it.

The Spurs played without backup point guard T.J. Ford. He will be out four to six weeks because of a torn left hamstring. Ford was injured Tuesday night in a loss at Milwaukee. San Antonio is already without top scorer Manu Ginobili for several more weeks because of a fractured fifth metacarpal.

Gary Neal had moved into the starting lineup to take Ginobili's spot, but with Ford out, Neal returned to the bench to assume backup point guard duties. Leonard started for the Spurs.

The Spurs also added Malcolm Thomas, a 6-foot-9 rookie forward. Thomas, who teamed with Spurs rookie Leonard at San Diego State, had been playing for Los Angeles in the D-League. "He's an athletic young man who has a lot of energy, has some good skills, so we'll take a look at him," Popovich said. Neither rookie played against Houston. ... With a free throw with 4:54 in the game, Duncan moved past Larry Bird for 27th place on the scoring list. Duncan has 21,888 points.
